"Cascaded trajectory refinement" was invented by Ethan Miller Pronovost (Redwood City, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "Systems and techniques for determining predicted object trajectories are disclosed. A vehicle computing system determines an initial predicted trajectory for an object detected in the environment and determine a predicted location for the object at the endpoint of the trajectory.
